[Repeater-Builder] Micor test set question

[georgiaskywarn]

I am wanting to meter the signal level on my Micor.  (to be able to
squeeze every drop out the the rx cans)  The test set number is
TLN1857A and TLN5900A.  From what I thought was the correct setting
(in position 6 (if you include the -4 and +4 as 2) or set on the
number 5) and show no change in the metering when a weaker signal
comes in.  It pretty much stays on about 44uA.
Ideas?
Thanks,
Robert
